How Do I Send a Text Message to a Cell Phone Without Having a Cell Phone?

Using a Texting Website
1. Go to a text-messaging website such as Onlinetextmessage.com, Txt2day.com or Textforfree.net.
2. Enter the mobile number of the intended recipient of your text message, the wireless carrier for that cellphone, your email address, the message you want to send and any other information requested by the website. Click 'Send' or the equivalent button.
3. Review any special offers or other information displayed on the page that appears after the text message has been sent. The website might ask you to try a subscription to its services. You don't have to sign up if the website offers free texting. Your message should have already gone through if you clicked 'Send' in the preceding step.
Using Skype
4. Install Skype on your computer if you do not have it. Go to Skype.com, roll your cursor over the 'Get Skype' tab, select your operating system and click 'Download Skype.' Follow the installation instructions.
5. Add contacts you would like to text message. When you first open Skype, the program will ask if you want to add contacts from your email addresses or social networking service, so you can do that if you wish. You can also search for contacts on Skype or create new ones. Make sure that the contacts you would like to text have cellphone numbers in their profiles. To do this, click on the contact, select the 'Mobile' tab, click 'Add a phone number' and enter the 10-digit number.
6. Add credit to your Skype account. Skype will deduct a few cents from your balance every time you send a text. You can 'Buy Skype Credit now' on your Skype home screen; simply have a contact highlighted and click on the 'Mobile' tab. The link will be at the bottom of the screen. You can also add credit to your account by clicking 'Add credit.' Follow the prompts and enter the appropriate information to add credit.
7. Write a text by highlighting a contact on your Skype home screen, selecting the 'Mobile' tab and writing your message in the box at the bottom of the screen. Click on the bubble to the right of the text box to send your message.
